Well, No ****, and there I was .... Changing out some old hoses to SRI Hoses, and Oh!? Wait! What the heck? [insert sound of screaming wallet] While I am there ...... [insert sound from earpiece of fav car parts dealer on Speed Dial] And before I knew it, I ended up well over butt deep in a 30K Major and even well beyond that in many areas. I have removed car parts scattered in every nick and cranny of the house. Wifey is pissed. We all know what THAT means...... Oh well. [sigh]. I need an impact wrench. Cordless. One that can RELIABLY generate the torques required to put everything back RIGHT on a 308 IAW the WSM. The highest torque I found in the 308GT4 WSM was 20 kg-meters which = 144.6602 lb-ft or 1735.9248 lb-in Reason for cordless is involved (I have 110v/220v issues) and I do NOT want to shell out the bucks for 220v corded as I may have to move back to the USA in a few years eek: HORROR!!!) thus rendering it useless. Air versions have the same voltage issues (got to compress the air, right?) as corded. Plus the prices over here are sadly absolutely insane for decent power tools. Any suggestions? Been reading lots of reviews on-line that have me just more confused. Please help .....
to put it back, you need a torque wrench. Maybe 2 or more. To remove it, you may need an impact wrench. IR is best.
Got two torque wrenches.[pats tool box] All cam cogs/sprockets, all six, are being replaced. That is why the impact wrench need. Who is "IR." This is the VERY First car I have EVER WRENCHED other than changing oil so I am not much of a Tool Guy .... YET. But, I have been CALLED a "Tool." Go Figure.
I think by IR he means Ingersoll Rand. Here's a link to their cordless impact guns: http://www.ingersollrandproducts.com/IS/Category.aspx-am_en-30698
Makita makes an excellent one. Bosch and Makita were top rated in a recent comparison test done by Car & Driver.
Impact wrenches are generally frowned upon for installing items that require a certain torque. Too much torque can warp or crack items or snap bolts. Not properly threading a bolt can cross thread beyond your wildest immagination. I won't go to a tire shop that installs wheel lugs on steel rims with an impact wrench. A torque wrench should do everything you need. Ferrari work is slow and methodical unless you are part of an F1 team swapping an engine for the next round in 5 minutes. I have a compressor and I think I still have an impact wrench. Haven't used it in over 10 years. Just my opinion. I like it that SRI hoses are traveling the world. Installed mine a bit over a year ago.
I agree, and to be clear I use my Dewalt impact for loosening lug nuts only and occasionally a stuck bolt if its 15mm or bigger. I never use it for tightening anything.
Heard Ya Fellas, LOUD AND CLEAR. Seriously, THANX. Me too. Several kits have made it over here that I know of. The BEST, just NEVER can sit still.
Good boy!! Forget the impact wrench for putting things back on the engine. Remember, most of what you are tightening, either bolts or nuts on studs, are threaded into aluminum. It doesn't take much extra torque to tear a stud out of the block or strip a thread hole in aluminum. And then, instead of loving your impact wrench, you'll find yourself learning a whole new art -- inserting Helicoils. Stick with the old fashioned torque wrenches for things that need to be torqued. And remember, most of the torque specs in the manuals are in Newton/Meters. There are some easy conversion programs on the internet or Iphone apps that help get them over to Pound/feet or point/inch, as the case may be. Have fun, and don't forget to post pictures of your projects as you go along!!!!
Mark, IR = Ingersoll Rand but I don't think they do electric. They are one of the top dogs in pneumatic tools As others have pointed out, impacts (electrics or air) are not always the best assembly tools. BUT, there are times when they are the right tool for assembly and are invaluable when taking things apart. I have the whole series of Dewalts. 1/4, 3/8, and half inch. The 1/4 is my weapon of choice for both tear down and reassembly of the Hewland on the race car. There simply is no better tool for all those case nuts. I started with the Dewalt 1/2 inch as it had the best torque in its class at the time (don't know about now as I stopped doing research after I purchased). I liked it so much I bought the others and the batteries are all interchangeable. Torque on the electrics is still significantly below the pneumatics, but sometimes you just don't need 600 Ft/Lbs... when you do, my choice is my Brunnhoelzl 60/40. For most of my reassembly on the Ferrari... by hand only. And usually its all 1/4 drive stuff. Rick
For air the IR is the best option, I have a couple of the Ti ones, much quieter than the std versions. IR does have cordless guns, getting more common as places like salvage yds don't have air lines running all over the place. or some job sites don't have the need to add the expense of having a portable air compressor to fuel. link: http://www.ingersollrandproducts.com/IS/category_nolinks.aspx-am_en-21016
I have an 18 volt Milwaukee that works well for most disassembly. I would never trust one for assembly as you really don't how much something is or isn't tightened. They now have a more powerful 24 v model. I've heard good about DeWalt but have no experience with that particular tool from them.
Dont be down on impct guns. I have a snap on and use it all the time. The issue is how they are used. The good ones have variable power. If you set it on max and keep it on you can twist the bolts off your hubs, if you use it gently and use a torque wrench when you have the car on the ground you will be fine. If you are in a hurry ,use a torque extender wrench of the right color for the torque you need. How do you get by to remove an axle bolt on a rear hub or the crank bolt on the front of the engine without an impact gun?(yes you can have the starter break it loose) I have a Sears non- air for those light days.
I concur, IR are the best rattle guns around. Errrrrr, or impact wrenches are you American's call them. They may be a little more pricey, but certainly well worth it. I dont know what they are worth over there in your Country.
Not a problem mate. We use IR guns at work. Simply the best out there. I bought one for myself 10 yrs ago after seeing them in action. I have used mine at home recently are buying a new/bigger air compressor. It sat for 7-8 yrs before I used it. Cool story- The Snap On tool van came to our work 10 yrs ago during my apprenticeship. He eventually saw my boss using his new IR rattle gun. He said I bet you $50 this Snap On gun can tighten or loosen any wheel nut tighter/quicker than his new IR gun. Of course my boss said DEAL! He tightened a wheel nut with his IR gun and our Snap On rep tried to loosen it with his Snap On gun. He couldnt do it after a min or so trying. Boss connected the IR gun back up and it loosened the wheel nut straight away. He then let Snap On man tighten the wheel nut, my boss loosened it straight away with the IR gun. He then told the Snap On man to get back into his truck and **** off! After seeing that, I put an order in for a 1/2" IR gun. The Snap On man ended up giving my boss $100 off some tools in his truck and me $50 off a screw driver set.
Beware the Chinese made IR tools. They make a variety with the best still US made. You will pay a premium and worth it. I have found a simple 3/8 drive speed handle to be one of the best bang for the buck tools in existence.
Hello Mark, since you are in Germany, I have the following source for 'Ingersoll Rand' tools. www.rsonline.de I got mine from there, though TROST stocks them also, but at less interesting prizes. I have a 2130XP and can recommend it. Undoing the most badly rusted bolts on winter drivers never represented a problem with this impact wrench. Best Regards Martin
